For those wanting to add page numbers to existing PDFs, Smile has released new versions of PDFpen and PDFpenPro, their PDF manipulation software. Version 5.5 adds the capability to put page numbers in either the header or the footer of the page, and the page numbers can start on any page. Visually, page numbers can be aligned left, right, or center, or even inside or outside for facing pages, and they can be formatted as Roman numerals, letters, or Bates Numbering. Also new in this update is initial support for full-screen mode in Mac OS X 10.7 Lion, along with some unspecified bug fixes. ($59.95/$99.95 new, free update, 41.5 MB)
Go Back and Forth Fast in Preview
If you're reading a PDF in Apple's Preview software, and you follow a bookmark or an internal link to move around within the PDF, you can quickly return to where you were by pressing the keyboard shortcut Command-[ (that's Command-Left Bracket). Or, you can choose Go > Back.
The command works iteratively, so you can go back to just the previously viewed page or if you issue the command again, to the page before that, and so on. There's also an equivalent Go > Forward (Command-]).
